Patent number: 9527012Abstract: A system operating as a centrifugal, liquid-liquid separator may be controlled, and even optimized, by automatic control of back pressure to establish an optimum position of the dispersion band therein. Optimizing to minimize impurities (from each other) in each of two separated phases is possible, even simultaneously, by reliance on a processor setting the settling lengths of both heavy and light phases at the same value. Settling length, defined in accordance with the invention, reflects a settling velocity multiplied by a residence time. Equating these lengths, for droplets of each in the other liquid, provides superior results over conventional settling theory maximizing settling area. Equalization of residence times did not provide an improvement over conventional settling theory.Type: GrantFiled: December 12, 2013Date of Patent: December 27, 2016Assignee: ECONOVA, INC.Inventors: C. Michael Miller, D. Andrew Bell, Ngai Keung Tam

Patent number: 9446417Abstract: Centrifuges have been designed in the past for centrifuging multi-welled containers, but they are limited in centripetal acceleration or have a large footprint. The invention provides a centrifuge with a high centripetal acceleration and imbalance tolerance while maintaining a small footprint and being able to integrate with laboratory automation equipment. Methods and apparatuses for centrifugation include a rotor assembly positioned within a shield assembly suspended in a centrifuge. The rotor assembly is operably connected to the motor for rotating payloads (e.g., multi-welled containers) around an axis. The shield assembly is positioned such that the center of mass is aligned with the axis of rotation of the rotor assembly and the plane containing the rotational imbalance force vector. This alignment allows rotation of the container with an acceleration of at least 2000 g (or at least 3000 g, 4000 g, 5000 g, etc.).Type: GrantFiled: January 24, 2013Date of Patent: September 20, 2016Assignee: BioNex Solutions, Inc.Inventors: Stephen Gaudio, Eric Rollins
